Construction and Demolition

Construction and demolition projects generate heavy, awkward debris in short, intense bursts. SANTO mobile conveyors and feeders link excavators, crushers and screens to keep material moving on tight, changing sites.

Site dynamics and material mix

C&D material is heterogeneous — concrete, brick, steel,木头 and fines — arriving in surges as structures come down. Sites are temporary, constrained and constantly reconfigured, leaving no room for fixed plant.

Reuse targets and landfill costs make on-site crushing and separation valuable, but only if material reaches the crusher and screen without excessive loader haulage that burns fuel and time.

• Heterogeneous, surge-loaded debris of mixed size and density
• Temporary, cramped sites reconfigured week to week
• On-site crushing only pays if feed reaches plant cheaply

Mobile conveying on the demolition site

A low feeder track stacker takes direct excavator loading of rubble and feeds the mobile crusher at a steady rate, while grasshopper conveyors carry crushed product to screening and stockpile without extra drives.

For separation, wheeled mobile conveyors link magnetic and air-sort stations, and the tracked stacker builds clean aggregate and fill piles for reuse or sale, with the whole train packing up when the job finishes.

Equipment choice for C&D duty

Concrete and brick are dense and abrasive, so specify impact beds, abrasion-resistant belt covers and heavy-duty idlers. Belt widths of 800–1200 mm at 100–600 t/h suit most crushing and recycling trains.

Tracked chassis cope with uneven, debris-strewn ground; low feeders ease direct excavator loading of heavy rubble. Belt scrapers and sealed bearings survive the dusty, gritty environment.

• Use impact beds and abrasion-resistant belt for concrete and brick
• Choose tracked chassis for uneven, debris-covered ground
• Low feeders simplify direct excavator loading of heavy rubble

Reuse, safety and project ROI

Continuous conveying feeds the crusher steadily so more rubble becomes saleable aggregate and fill, cutting landfill tipping fees and haul-away cost. Fewer loader cycles reduce site traffic and incident risk.

Because the mobile train packs up and moves to the next project, one fleet serves many jobs, spreading capital across far more tonnage and paying back through reuse revenue and lower handling cost.

Frequently Asked Questions

Can mobile conveyors feed a mobile crusher?

Yes. Low feeder track stackers take direct excavator loading and meter a steady rubble feed to the crusher, keeping the plant at full capacity.

How does this help meet reuse targets?

Steady feeding means more C&D debris is crushed into reusable aggregate and fill on site, cutting landfill and haul-away costs.

Will tracked units cope with rough ground?

Yes. Tracked chassis handle uneven, debris-strewn surfaces where wheeled units would struggle, keeping the train mobile across the site.

What rate suits a C&D recycling train?

Configurations from roughly 100 to 600 t/h cover concrete, brick and mixed debris duties.
